"Doctor Who" is a British Broadcasting Corporation series following the adventures of a mysterious time-traveller known only as "the Doctor" and the various companions who travel with him. It is among the world's longest-running science-fiction television series and has a worldwide fan following.
The show began in 1963 and ran for 26 seasons until it was put "on hiatus" (and not officially cancelled) in 1989; a television movie was made in 1996. While it was off the air, books and audio dramas continued the Doctor's adventures.
The programme was relaunched in 2005, with a full season and a Christmas special each year through 2008, four specials in 2009, and a fifth series in 2010 - 2014.

The original 'adult' novels are published monthly in two strands, the "Past Doctor" novels, which slot in between televised stories, and the Eight Doctor novels, which follows on from the end of the series.
Virgin Books published the series from 1991 until 1996, when they launched a spin-off series starring Professor Bernice Summerfield, due to the license being taken back by the BBC, who have been publishing the series ever since.
